Intraspecific variations in flowering phenology of African pear (Dacryodes edulis (g. Don) H.J. Lam) flowering in south east Nigeria

A survey was carried out in two states, six locations of south east Nigeria during the normal flowering period for three (3) consecutive years to evaluate intraspecific variations phenology African pear flowering. The different types species growing forest, distant and nearby farms, including homesteads were used. 60 trees 180 flowered branches sampled survey. Parameters collected include time flowering, number flower per inflorescence, inflorescence length panicle. Data analysed using analysis variance, regression correlation. Standard errors percentages calculated where appropriate. Based on observed floral nature, distinct tree identified – female, male hermaphrodite trees. varied within between locations. This ranged from December March 2013 2015 study. Strong positive relationship exist inflorescence. Significant (p<0.05) differences mean panicle Abia state. length, statistically same 2014 Imo State.
